"Great Basin NP", ( ain't ever heard of it) sounds like it's just outside and West of Laramie. AND, since it's in Wyoming (???). and that's where "I'd rather be", it'll also on MY bucket list. If it's where I'm assuming, even if there is no fishing there to speak of, I know a whole bunch of spots very close to there (???)

PS: Is it where I think it is???
PS: Again: And after further review.....................never mind :>)
